Title: Improvements in electric switches
IPC: H01H5/18
Filed: 1928-04-05
Abstract: 288,315. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Mottlau, A. J.). April 9, 1927, [Convention date]. Thermal switches; switches, quick-action.- A device is actuated with a. snap action by relative movement of supporting members, to which is rigidly connected a curved resilient bridging-member carrying the moving contact, so as to cause an initial movement of the bridging-member to actuate it positively through an unstable position to effect the actuation of the contact. In Figs. 1 - - 3, a resilient frame 11 has three bridging members 13 - - 15, whereof 14 is wider, as shown, or narrower, than the others, and is screwed to blocks 17 on the base at depressed portions 16, the strips being laterally bent as shown in Fig. 3. One end of the frame 11 is held deflected by a bolt, 22. A hammer 23 is riveted to strips 13, 15 and is threaded intermediately to receive a bushing 26 which is locked by a nut 27 in any desired position with respect to the strip 14. One contact 29 forms the head of a bolt 28 carrying nuts 33 and extending through strips 14 and the bushing 26. By depressing either end of the frame 11, Fig. 3, the - strips 13, 15 snap upwards to move the bushing 26 against the nuts 33, and the impact causes an initial snap movement of the strip 14 in advance of the movement it would derive from its own resiliency as it passed through an unstable position. Also, the strip 14 is thus caused to maintain the contact pressure until the impact occurs and premature disengagement is avoided. In the form shown in Fig. 7, the hammer 31 is apertured to receive the bolt 28 and is located between two pairs of nuts 36, 37, against the former .of which it rests in the closed circuit position. In another form (Fig. 9, not shown) the strips are riveted or welded at each end to the frame. The switch may be manually or mechanically operated, and may be responsive to temperature, pressure, or like conditions. The switch may be made bimetallic so as to respond to thermal .changes.

Abstract: 484,354. Adhesive-tape dispensing- machines. LINK, L. April 13, 1937, No. 10517. Convention date, April 16, 1936. [Class 73] [Also in Group XVI] A tape-dispensing machine has a manuallyoperated feed mechanism comprising a wheel provided around its periphery with a number of spaced finger-pieces having slots or grooves therein, and the finger when turning the wheel is engaged by an abutment which extends into the grooves or slots in the finger-pieces. The machine comprises a casing 10 having a housing in which rests a roll of gummed tape 15, the top 39 of the casing being hinged to the main part to facilitate insertion of new rolls. A feedwheel 24 is secured to a gear-wheel having internal teeth meshing with a pinion secured to a feed-roll. The latter co-operates with an upper feed-roll mounted in a casing portion 20 which is hinged to the top 39 and spring-pressed downwardly The tape 15 passes between the feed-rolls, past cutting-means, between a weighting-element 17, and over a moistened brush supported in a container 38 of liquid. The wheel 24 has a number of finger-cams 26 around its circumference, the surfaces 27 of the cams being shaped to fit a finger, and the cams each having a central slot to allow an abutment 31 to extend inwardly of the outer tips of the cams. The abutment is attached to a lever 34, both being secured to one arm 32 of a bell-crank lever 32, 35 pivoted at 33 to the casing wall, the arm 35 being bent to pass inside the casing through a slot. Near the end of the arm 35 a link 37 adapted to operate a cutting-blade 19 is pivoted, the blade co-operating with a fixed bar 191 for cutting off lengths of tape 15. A spring 36 keeps the link 37 vertical and hence the abutment in one position. In operation, a finger is placed on one of the cam surfaces 27 and moved towards the abutment 31 to rotate the wheel 24 and feed the tape. The abutment stops the finger, and any momentum of the wheel 24 is overcome by the undersurface of the next cam 26 bearing on the finger, although the undersurfaces are shaped so that the finger cannot be trapped. The finger is next drawn slightly away from the wheel and pressed on the lever 34 to operate the cutting-blade 19 to sever the tape which has been fed from the casing.

Patent GB-106853-A (GB)
IPC: F42B30/14
Abstract: 106,853. Walker, L. G., and Hughes, J. E. June 3, 1916. Grapnels.-Relates to grapnels adapted to be shot over an obstacle, such as wire entanglements, so as to engage it when drawn back, and consists mainly in providing mechanism which is controlled by an explosive charge in the grapnel so that it may be disengaged from the obstacle when required. In the construction shown in Fig. 1, an outer tube A has barbs F pivoted on radial brackets G, a cable (not shown) being attached to the forward end and running through a slidable collar D. An inner tube B has at one end a cap b adapted to fit a gun-barrel, and has a head E connected by a bolt I to a central rod H. This rod acts upon the cranked ends f of the barbs F by means of a disk h, and the parts f are also engaged by a disk e controlled by a, spring J. When the projectile is discharged from a gun, the parts remain during flight in the position shown, but on impact the head E is driven in, causing the barbs to be extended by the action of the disk e. If the barbs have been caught in wire entanglements, these can be dragged back by hauling in the cable. To free the barbs from the entanglements and recover the projectile, the bolt I is blown out of locking engagement with the rod H by exploding a charge in the chamber k. This may be effected by means of an electric igniter K, to which a current can be conducted through the hauling cable, returning through earth. A sliding contact is provided in the head E. Mechanical means may, alternatively, be used for firing the charge. When the bolt I has been ejected, the disk h is free to move further inwards, so that the barbs can turn rearwardly into a non-gripping position. Fig. 7 shows a modification designed to minimize the strain on the bolt 1. Instead of being in the head E, the bolt is arranged in the shank as shown, passing through the inner tube B, through a spring-controlled sleeve M which acts upon the barb-levers f, through a part N which has an inclined surface forming a seating for ball-bearings P and into a charge-chamber k in the central rod H. The thrust of the barb-levers f when the grapnel is being dragged back is' thus transmitted to the bolt I through a member o and through the balls P and chamber N, the slope of the bearing-surface reducing the strain on the bolt. In this construction, the charge in the chamber k for ejecting the locking-bolt is fired by an electric igniter K provided at the base of a long adapter tube Q. The current passes through the cable and through conductors n the shank A and the tube Q. the contact between the conductors in the parts A, Q being a slidable one. Suitable insulation is provided. ln a further modification, instead of the parts o, N, Fig. 7, there is an internally-threaded sleeve, provided with ball-bearings at its ends, and engaging with a quick thread on the central rod H.

Abstract: 780,470. Coin-freed apparatus. MURPHY & SONS (ENGINEERS), Ltd., J. and MURPHY, P. G. April 9, 1956. No. 10801/56. Class 27 [Also in Group XXXVII] An electric switch comprises a main rotor disc rotated contlinuously at constant speed, a conducting rotor disc urged resiliently into contact with the main rotor but held from rotation therewith by a stop adapted to engage the conducting disc at one or more spaced points thereon, and coin-freed tripping means adapted to disengage the stop from the conducting disc to permit rotation thereof to complete a circuit to, for example, lamps in a church shrine. As shown, the disc 5 is keyed to a constantly rotating shaft 2 and the conducting disc 8 is slidable on a hub 6 of disc 5 and biased against the latter by a spring. Stop pins 11 on the disc 8 co-operate with a stop 12 slidable to an extent limited by pins and slots 32, 33 on a bracket 13 carried by a slide 14 which is biased to the left by a spring 17. Normally, the disc 8 tends to rotate clockwise but is held by a pin 11 engaging the underside of stop 12. In this position of disc 8, a fixed spring contact 26 is opposite a recess 28 or 29 in the edge of disc 8 so that the circuit to a lamp 25 is broken. The disc 8 is released by moving the slide to the right by means of a coin freed mechanism. A slot 20 in the slide 14 is normally slightly out of register with a slot 21 in the casing 1 so that the insertion of a coin 31 pushes the slide 14 to the right. The coin falls into one of two slots 22 in disc 8 and, when the latter rotates, falls out into a container. The rotation of disc 8 is stopped when the same or the next pin 11 again strikes stop 12.
